Alicia is currently serving time in prison after lashing out at Val Pollard, while Natalie Anderson - who plays the feisty character - is on maternity leave after giving birth to a baby boy in August.
Wolfenden's alter ego David Metcalfe tied the knot with Alicia in a sham wedding a few months ago, and he later discovered that she genuinely was in love with him.
Alicia could be heading for fresh heartbreak upon her return as David is now dating Priya Sharma (Fiona Wade).
Wolfenden, asked about the storyline's future, commented: "Genuinely we don't know! Natalie comes back from her maternity leave soon, and we don't know what's happening once she comes back - whether David will decide that he does love her really, or if he doesn't.
"I think there'll definitely be a catfight between Alicia and Priya! They're not going to pass up a storyline of two good-looking girls having a fight, are they?"
The actor added that he would not rule out a future return for David's previous girlfriend - Alicia's sister Leyla Harding (Rokhsaneh Ghawam-Shahidi).
He said: "The door was left wide open for her, and I know that they've talked about it. As of yet, there's no scripts with her in it but you never know - I hope so. I had a ball working with Rokhsaneh."
